    5 times a number is that number minus 3

    The phrase a number means an arbitrary variable. Let's call it x.
    • 5 times a number: 5x
    • That number means we use the same number from above which is x
    • That number minus 3: x - 3
    • The phrase is means an equation, so we set 5x equal to x - 3
    5x = x - 3
